The ultimate switch for your heavy pumping needs

A bilge full of water is troublesome and the manual bilge switch is too much of a hassle to use and takes a lot of time to completely drain the water out of the boat. That's why boat owners use the Johnson Ultima Automatic Digital Bilge Switch -- it easily detects a certain water level and kicks in automatically.

The Johnson Ultima Automatic Digital Bilge Switch uses the patented Mirus field effect detector cells that produce micro-electrical fields which automatically turn the bilge on the moment a disruption caused by water and other fluids is detected. The detector cells are totally sealed, are not affected by oil or foreign debris and are never in contact with the water, resulting to a smooth operation every single time.

Field effect detector cells
Mirus detector cells are composed of an active device and an electrode surrounded by a second electrode. The applied circuit creates an electric field around the cell.

The Johnson Ultima Automatic Digital Bilge Switch activates at a 50 mm (2") fluid level and deactivates at a 20 mm (3/4") fluid level with an eight second delay to prevent false starts. Compared with the archaic bilge swit…
